Methods, systems, and devices for network maintenance are described. A controller may receive an indication that the performance of a network device has decreased. The indication may include case identification data associated with the network device. The controller may request proactive network maintenance (PNM) data associated with the network device based on receiving the case identification data. The controller may transmit the PNM data to a machine learning (ML) engine. The ML engine may transmit, to the controller, an indication of a predetermined operation predicted to improve the performance of the network device. The controller may transmit the predetermined operation to a client device based on receiving the indication of the predetermined operation. The ML engine may receive feedback indicating whether an execution of the predetermined operation improved the performance of the network device. The ML engine may a training data set based on the feedback.
